Mesotrione is an herbicide sold under the brand names Callisto and Tenacity that was brought to market by Syngenta in 2001.[1] It is a synthetic analog of leptospermone developed to mimic the effects of this natural herbicide.[2] Mesotrione is a member of the class of HPPD inhibitors, which all work by inhibiting the plant enzyme 4-hydroxyphenylpyruvate dioxygenase.[3] In plants, HPPD is necessary for carotenoid biosynthesis; carotenoids in turn protect chlorophyll from being degraded by sunlight.[4] When an HPPD inhibitor is sprayed on a plant, it prevents carotenoid from being made, chlorophyll degrades and the plant dies.

Sales by Syngenta were more than $400 million per year in 2011 but worldwide patent rights started to expire in 2012, opening the market to generic competition.[1]
